Detailed ways

Before introducing this application, the related knowledge related to the embodiments of the present application is introduced below:

The HARQ feedback codebook (also referred to as a HARQ-ACK feedback codebook): the terminal device may feed back the decoding result of the at least one data unit transmitted by the network to the network device in a UCI, and the at least one data unit may be different from Downlink subframes, different codewords under MIMO, or different carriers under carrier aggregation. The decoding result included in the UCI is the HARQ feedback codebook. The decoding result of each data unit may be ACK or NACK. The decoding result of each data unit may be referred to as HARQ feedback information.

The data unit in the embodiment of the present application can be understood as a TB, or a code block group (CBG), or other data units, which is not limited in this application.

The preset time period in the embodiment of the present application can be understood as a HARQ multiplexing window or any other form of time period. The HARQ multiplexing window may also be referred to as a time window, or a binding window, or an Associated Sets.

The time unit in the embodiment of the present application may also be referred to as a time scheduling unit, and the time unit may be one or more time slot slots, or one or more minislot mini-slots, or a transmission time interval (TTI). ), or one or more time domain symbols or subframes, etc.

In the embodiment of the present application, the uplink time unit may carry the UCI or the HARQ feedback codebook, that is, the terminal device needs to feed back the HARQ feedback information of the data unit transmitted by the one or more downlink time units on the uplink time unit, and the downlink time unit is used. The set is called the HARQ multiplexing window described above. Specifically, FIG. 1 is a schematic diagram of a HARQ multiplexing window according to an embodiment of the present disclosure. As shown in FIG. 1 , the HARQ multiplexing window includes five time units, wherein five time units include an uplink time unit and a downlink time. The unit, the UCI or HARQ feedback codebook corresponding to the HARQ multiplexing window is transmitted through an uplink time unit.

In an embodiment, Dynamic Time Division Duplexing (TDD) means that the ratio of uplink and downlink time slots will dynamically change in multiple time slots to adapt to the changing communication service model in the cell. . In the NR, the network device can indicate the ratio change of the uplink and downlink time slots of the terminal device by using the Group Common Downlink Control Information (GC DCI), as shown in Table 1.

Table 1

Table 1 provides the configuration of dynamic TDD for 10 consecutive time slots. "D" indicates the downlink time slot, "U" indicates the uplink time slot, and "*" indicates that the time slot can be flexibly configured as an uplink or downlink time slot. , "/" means the relationship "or".

At the same time, for a time slot, the uplink and downlink ratios of multiple symbols of its time slot may also send dynamic changes. The NR may send a slot format indicator (SFI) in the GC DCI to inform the terminal device of the uplink and downlink ratios of the symbols inside the slot.

The introduction of dynamic TDD will cause the number of time slots in the HARQ multiplexing window of a terminal device to actually transmit downlink data units to be constantly changing (because the available downlink time slots are constantly changing). Since the terminal device does not always receive the GC DCI, the terminal device may not be able to know the number of time slots or CBGs that can actually transmit the downlink data unit in the current HARQ multiplexing window. In order to ensure the reliability of the transmission of the HARQ feedback codebook, the number of bits occupied by the network device that may be configured for the HARQ feedback codebook is the maximum number of bits, resulting in an excessive overhead of the HARQ feedback codebook.

For the above technical problem, the embodiment of the present application provides a method and an apparatus for processing a HARQ feedback codebook. FIG. 2 is a schematic diagram of a network architecture according to an embodiment of the present disclosure.

Node B, HNB), baseband unit (BBU), base station (gnodeB, gNB), transmission and receiving point (TRP), transmitting point (TP) or small base station, etc. Including various types of access points (APs).

It should be noted that the network architecture described in this embodiment is for the purpose of more clearly explaining the technical solutions of the present application, and does not constitute a limitation on the technical solutions provided by the present application. The technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

Based on the above, an embodiment of a method and apparatus for processing a HARQ feedback codebook provided by the present application is described in detail below.

Specifically, FIG. 3 is an interaction flowchart of a method for processing a HARQ feedback codebook according to an embodiment of the present disclosure. As shown in FIG. 3, the method includes the following processes:

Step S301: The terminal device receives the downlink indication information sent by the network device, where the downlink indication information is used to indicate the downlink resource amount in the preset time period;

Step S302: The terminal device determines, according to the downlink indication information, the number of bits occupied by the HARQ feedback codebook corresponding to the at least one downlink data unit.

Step S303: The terminal device receives at least one downlink data unit that is sent by the network device in a preset time period;

Step S304: The terminal device sends the HARQ feedback codebook to the network device in the bit number of bits, and sends the first uplink indication information to the network device, where the first uplink indication information is used to indicate that the downlink indication information has been successfully received.

The detailed description is performed in combination with the step S301 to the step S303. The downlink indication information is used to indicate the amount of downlink resources in the preset time period, where the downlink resource is used to transmit the at least one downlink data unit. The downlink resource quantity may be a ratio of the downlink resource to the uplink resource in the preset time period, or a ratio of the downlink resource in the entire preset time, or the number of downlink resources, etc., the application does not do this. The downlink resource may be a time domain resource, a frequency domain resource, or a time-frequency resource. For example, it may be a downlink subframe, a downlink time slot, a TB, a resource block (RB), or a resource element (Resource Element). , RE), etc., this application does not limit this.

The downlink indication information may be a DCI, a terminal device specific DCI, or a GC DCI or the like. When the downlink indication information is the GC DCI, the network device may group the multiple CCs of the carrier aggregation (CA) into one group, and send only on one of the CCs within a preset time period in one group. A GC DCI. Or in order to improve the robustness of the GC DCI, the network device may repeatedly send the GC DCI. The repetition may be a repetition in the frequency domain, a repetition in time, or a repetition on different CCs. Alternatively, when the downlink indication information is a GC DCI, the network device may separately transmit the GC DCI for each CC.

The network device sends the downlink indication information to the terminal device, and the terminal device may successfully receive the downlink indication information, may not receive the downlink indication information, or may not successfully receive the downlink indication information, for example, the received downlink indication information. Is the wrong message. In this embodiment, if the terminal device successfully receives the downlink indication information, the terminal device determines, according to the downlink indication information, the number of bits occupied by the HARQ feedback codebook. For example, the downlink indication information indicates that the downlink resource amount corresponding to the downlink data unit is 13 time slots, and if each time slot corresponds to one bit of HARQ feedback information, the number of bits occupied by the HARQ feedback codebook in the preset time period is It is 13 bits.

The preset time period in the embodiment of the present application can be understood as a HARQ multiplexing window or any other form of time period.

The data unit in the embodiment of the present application can be understood as a TB, or a CBG, or other data unit, which is not limited in this application.

It should be noted that, in this embodiment, the execution sequence of step S302 and step S303 is not limited. For example, step S302 may be performed first, and then step S303 may be performed; or step S303 may be performed first, and then step S302 is performed.

Step S304 is described. Assuming that the terminal device determines that the number of bits occupied by the HARQ feedback codebook is 13 bits, the terminal device transmits the HARQ feedback codebook on 13 bits.

Optionally, the downlink data unit is a TB, and each bit occupied by the HARQ feedback codebook corresponds to one TB corresponding HARQ feedback information.

Further, the terminal device may further send the first uplink indication information to the network device, where the first uplink indication information is used to indicate that the downlink indication information has been successfully received. If the downlink indication information is the terminal device specific DCI, the first uplink indication information sent by the terminal device is feedback for whether the terminal device specific DCI is correctly received. If the downlink indication information is CG DCI, and the CG DCI is sent for a group of CCs, the first uplink indication information sent by the terminal device is feedback for the GC DCI. If the downlink indication information is CG DCI, and the CG DCI is sent for one CC, the first uplink indication information sent by the terminal device is feedback for all GC DCIs corresponding to all the CCs. That is, the first uplink indication information is sent only when the terminal device completely receives all the GC DCIs in the preset time period.

Optionally, before the step S304, the HARQ feedback codebook and the first uplink indication information are jointly coded or independently coded, and the coded HARQ feedback codebook and the first uplink indication information are sent to the network device. The HARQ feedback codebook and the first uplink indication information may be sent together or separately. It is assumed that the terminal device sends the HARQ feedback codebook together with the first uplink indication information to the network device, that is, adopts the same transmission physical uplink control channel ( The Physical Uplink Control Channel (PUCCH) or PUSCH transmission should independently encode the HARQ feedback codebook and the first uplink indication information. Based on this, the network device may first decode the first uplink indication information, determine the number of bits occupied by the HARQ feedback codebook by using the first uplink indication information, and then decode the HARQ feedback codebook.

For example, the bit 0 in the HARQ feedback codebook corresponds to the downlink data unit 0, and then the HARQ information on the bit 0 is the feedback information of the downlink data unit 0.
